claiming that it's just social pressure and the results are invalid results is a classic hallmark of the intellectually dishonest. It's an unfalsifiable claim that will always be unfalsifiable because the perception that trans people are an aberration can never be eradicated. It's also something that, even in a best case scenario, can never be known even by the most fervent of the people who believe it. What this means is the claim is intrinsically inseparable from preferential interpretation, and so refuting the claim will always have justification equal to that of making the claim if not better.
